ELECTRIC RELAY.

Specification of Letters Patent.

Patented June 4, 1907.

Application filed June 8, 1905. Serial No. 264,279,

To all whom it may concern.-

Be it known that I, Isinon KITsEE, of the city and county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Electric Relays, of which the following is a specification.

My invention relates to an improvement in electric relays. Its object is to provide means whereby impulses received may be relayed in an cfiicient manner.

To this end my invention consists in the arrangement and features as will hereinafter be more fully described, illustrated in the drawing, and more clearly pointed out in the claims following the specification Referring to the drawings :Figure 1 is a perspective view of part of a receiving device, here shown as part of the well known siphon recorder used in cable telegraphy, and a relay embodying my invention. Fig.

illustrating this relay in a ditierent form. Fig. 3 is a perspective view of a modification of said relay with electro-magnetic receiver. Fig. 4 is a top plan view of part of the device illustrated in Fig. 3 with a modification. Fig. 5 is a top plan view of part of the movable art of a static device, such as a quadrant adhpted to be used in connection with the relayas illustrated in Fig. 3. Fig. 6 is a partial sectional and partial diagrammatic view of a device to clear the relay. Y

A is the well of a receiving device, well knownunder the name of siphon recorder and used in submarine telegraphy A-2 is the liquid contained therein; A1 is the siphon proper. Usually the liquid A-2 consists of nk adapted to make record on the moving paper but as in accordance with myinvention such record in unnecessary and the fluid has to be conducting, this iluid A-2 consists of any of the conducting liquids, such as slightly acidulated water or water made slightly caustic. B, B, are two conducting points, separate from each other by the space B1;E is a source of current.

C is an electro-magnetic device. In Fig. 1, the points B,'B, are connected respectively through wires 1 and 2, with the interposition of the electro-magnet G, to the source of current E. In this figure C-1 is the movable lever of the electro-rnagnet, normally, that is, whenthe device is not energized, against the sto D, and adapted to be brought in contact when energized with the stop D The armature 51 connected to wire 3 and the stop D-1 to wire 4. B-2 is a receptacle adapted to catch the fluid dropping through the space B1.

The operation of this device as illustrated. in Fig. 1 is as follows z-VVhen the siphon A1 is out of alinement with the space B1, then this space will remain free and non-conducting for the source of current E, but as soon as the siphon centers with its lower end in alinement with said space, then the fluid issuing from this siphon will bridge the space 13 1 and will make the same conducting for the flow of the current from E. This flow of current will energize the electro-magnet and the armature will be brought in contact with D1, thereby closing the circuit of which the wires 3 and 4.- are part. This circuit may contain any of the well known translating devices and source of current necessary for the operation of same. The contacts B, B, with their open space B1 is in reality the relay proper, and the liquid A2 is only the means to make this relay operative.

In Fig. 2, the relay consists of the contacts B, B, B, separated by the spaces B1, B-1. This for the reason that if a polarized relay is used, being normally centered in the middle, it should operate the relay, no matter if actuated to the left or right.

In Fig. 3 a receiving device, such for instance as a polarized relay is shown at A, but the movable part is provided with the shield F impervious to the li uid A2. Instead of, as in Fig. 1, in whic the liquid A2 is carried in accordance with the movement of part of the receiving device, in Fig. 3 the liquid A2 issues from a stationary source, through the funnel G. As long as the shield F remains directly above the space 13-1, the liquid will run through the groove f to any desired oint, but as soon as the shield F comes out o alinement with the space B l, then the li uid A'-2 will flow through this space into t 1e receptacle B 2.

In Fig. 4, the shield F is provided with the orifice f1, which orifice may be used either to carry a microscopic funnel or to be in itself the means through which the liquid will pass if this hole is in alinement with the space B-l.

In Fig. 5' I have illustrated the shield F in a modified form.

In Fig. 6, the armature C-1 is provided with the perforation H-2 for the purpose of The operation of this device is as follows l As long as the space B1 is free and unobstructed, adirect source of current cannot flow through a circuit connected to the contacts separated by such spaces and electromagnetic devices therefore inserted in such circuit will remain inoperative as long as.

these spaces remain unconnected, but. when either directly or indirectly, through the operation of the receiving device, a conducting liquid is made to pass through one or the other of the spaces B1, then the circuit will, for all intents and purposes, be closed and the flow of current from the source E willcommence and will continue till the liquid has passed the space B1.

Instead of liquid a fluid metal, such as mercury may be used. The selection of the kind of liquid to be used must be left to the person in charge of this device, for in different 10- calities or for different contacts, different liquids may be more ada table. As contacts, either carbon or p atinum are preierred, but any other material suitable for the purpose may be used.

It is nnpossible to state how great the distance between the points of contact B, B, should be, or how far apart these contacts shall be kept, as this distance has to vary with the requirements for each case. It suffices to say, thatwhere an easy flowing liquid is used, the contacts may only be separated about 1-32 inch, but as in such cases where the liquid may adhere to the points, thus bridging the space, even when not desired, I have recourse to the arrangement'as illustrated in Fig. 6, where the points B, B, are

carried bythe armature C'-1.of the electromagnet C., adapted to be actuated by the opening or closing of the space between these contact-points. When, in this arrangement, the space between the contacts is bridged by the liquid, the circuit therefore being closed, the armature C-1 will move downward and through this movement the s ace B-l will be cleared from any adhering l iquid globules.

It is understood that this relay may be used in any of the electric transmission as long as the receiving device issensitive enough to vary theflow of the liquid through the space B-1.

I have shown and forms of this relay, other forms may illustrated different but it is obvious that be adapted, the main and underlying principle being only that conducting points normally apart from each I Patent with the impulses received.

means at said receiving other shall be made to form a conducting path through the flow of a conducting liquid, and that this flow itself or the direction of this flow should be varied in accordance with the incoming impulses.

I have shown in Fig. 1 the contact-points B, as provided with means to adjust the air-space between same, which adjustment may be made to suit requirements.
